The two men are accused of killing 70-year-old Barbara Leslie of Surprise and 75-year-old Ruth Schwed of Albuquerque, New Mexico.

In a letter sent to Sun City Grand residents Friday, Gothic Grounds said the two men had been employed as field gardeners for less than a month at the time of the shooting. Their employment ended Feb. 5.

The company said they are cooperating fully with law enforcement in the ongoing investigation.
